多频天线及具有该多频天线的无线通信装置
摘要：
一种多频天线，其包括一馈入端、一第一接地部、一第二接地部、一第一发射臂、一第二发射臂、一第三发射臂及一第四发射臂。所述第一接地部及第二接地部相邻设置于馈入端的两侧，所述第一发射臂的两端分别固接于所述第一接地部及馈入端上。所述第二发射臂及第三发射臂均由所述第一发射臂向外延伸形成，并共享所述馈入端。所述第四发射臂一端固接于第二接地部上，并由该第二接地部向外延伸形成。所述多频天线工作时，信号自馈入端进入后，可分别沿第一发射臂、第二发射臂、第三发射臂及第四发射臂获得不同长度的传播路径，产生不同的信号电流及共振频率，以使得该多频天线具备多频操作特性。
摘要（英）：

A multiband antenna includes a base board, a feed member, a first grounding connector, a second grounding connector, a first radio member, a second radio member, a third radio member and a fourth radio member. The feed member, the first grounding connector and the second grounding connector are all electronically connected to the base board. The first radio member is electronically connected to the feed member and the first grounding connector. The second radio member is electronically connected to the first radio member. The third radio member is electronically connected to the first radio member. The fourth radio member is electronically connected to the second grounding connector. In use, the multiband antenna sends/receives wireless signals in different working frequencies by the radio members.
